Gold Flotation - Mineral Processing and Metallurgy

A gold carbonaceous sulphide ore from California carrying free gold yielded a 93 per cent recovery into a concentrate at 14.4:1 to ratio of concentration after conditioning with 0.50 lb. per ton of reagent 645. In each case the ore was ground to about 70 per cent minus 200 mesh and conditioned at 22 per cent solids with the reagents as indi ed.

Surfactants and Mine Dust Control and Effect on Flotation

Dust measurements in mines clearly indi ed that the major mineral dust exposure is due to loading and transport of the ore from the mining areas. One approach to the solution of this dust problem is the appli ion of water sprays to reduce dust dispersion. Wetting of broken rock is very effective in preventing fine dust from becoming airborne by binding it to the larger lumps. The .

Gold Extraction and Recovery Processes

Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm. This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation.

as chalcopyrite, bornite, and chalcocite. The copper ore consists of gold and silver mineralization as well as magnetite. ORM will perform metallurgical testing in order to determine if the magnetite will be economically feasible for recovery. The copper ore will be processed through crushing underground , grinding, flotation

Dolomite mining process is the solution of separating dolomite concentrate from Dolomite ore. Based on mosaic structure of the Dolomite mine and years of mining process experiences, we applying Dolomite mining process of two-stage crushing, washing, then three-stage separating, flotation process will be used to process Dolomite with complex .


copper close to the surface. The sulfide and oxide ore will be mined through conventional open pit mining techniques. Concentrate ore mostly comprised of sulfide ore will be processed by crushing, grinding, and floatation to produce copper concentrate product, which contains copper, silver, and possibly small amount of gold, and molybdenum.
